Background: Blackgram is an important crop among kharif pulses and is usually grown on marginal and sub-marginal lands without proper weed management under rainfed situation. Broad bed furrows had greater influence on plant growth over farmers practice. Weed management through mechanical or manual is normally tedious, labour consuming and costlier. Keeping this in view, the present study was envisaged to investigate integrated effect of land configuration and weed management regimes on productivity of urdbean. Methods: A field experiment was carried out during kharif seasons of 2016 and 2017 at Regional Agricultural Research Station, Lam, Guntur on effect of land configuration and weed management on performance of urdbean (Vigna mungo L.Hepper). The treatments included two land configurations i.e., flat bed and broad bed furrow method allotted as horizontal plots and four weed management practices i.e., weedy check, pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE, imazethapyr 10% SL @ 55 g ha-1 at 15-20 DAS and pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS allotted as vertical plots replicated four times in a strip plot design. The comparison of treatment means was made by critical difference (CD) at P less than 0.05 by using standard statistical procedures. Result: Based on the results, it can be concluded broad bed method of land configuration proved its superiority over flat bed method by producing 12.8 per cent higher grain yield besides empowering growth and yield attributes. Among the weed management practices, the highest grain yield (1280 kg ha-1) recorded with pendimethalin 30 EC @ 1.0 kg a.i ha-1 PE fb imazethapyr 10% SL @ 55g ha-1 at 15-20 DAS along with maximum monetary returns and B:C can be recommended for urdbean.

The experiment was aimed at assessing the effect of zinc solubilizing isolates on the available zinc content, growth and yield attributes of paddy. The study was conducted using a randomized block design at the experimental plots of Agricultural Research Station, Dhadesugur. The isolates namely MZSB 6 and MZSB 8 were tested for in vitro solubilization of the zinc and later brought under field condition. 25-day-old paddy seedlings were dipped in lignite based biofertilizer slurry and transplanted according to treatments. Data on growth and yield parameters of paddy were taken at regular intervals of 30 DAT, 60 DAT and 90 DAT and available plant zinc content were estimated using the Inductively Coupled Plasma Mass Spectrometry. Growth and yield parameters of paddy showed a significant increase in the treatment that received combination of MZSB 6, MZSB 8 and 75% recommended dose of fertilizer (RDF) as compared to control and other treatments. Results also showed the highest available zinc of 46.18 mg kg-1 of plant estimated using the ICP-MS. Thus, the results revealed that the combination of both isolates with 75% RDF was found to be efficient in enhancing growth and yield of paddy.

A field experiment was carried out in Grey Terrace Soil of Joydebpur and Non Calcareous Grey Floodplain Soil of Agricultural Research Station, Burirhat, Rangpur during the rabi season of 2010-2011 and 2011-2012. The objectives were to evaluate the effect of boron on the yield and yield attributes of BARI Hybrid Tomato-5 as well as to determine an optimum rate of boron application for maximizing yield. Three varieties of BARI Hybrid Tomato-5 viz., Epoch, NS 815 and BARI Hybrid-5 and five levels of boron (0, 0.5, 1.0, 1.5 and 2.0 kgB ha-1) along with a blanket dose of N220 P60 K120 S40 Zn4.0 kg ha-1 and cow dung 5 t ha-1 were used in the study. Results revealed that NS 815 performed the best with 1.5 kg B ha-1 that produced 79.7 t ha-1 at Joydevpur whereas at Burirhat Epoch performed best (101 t/ha). The said combination increased 31.7% and 57.8% yield over the control at Joydevpur and Burirhat, respectively. However, from regression analysis, a positive but quadratic relationship was observed between yield and boron levels. The optimum dose of boron was appeared to be as 1.37 kg and 1.54 kg B ha-1 for Joydevpur and Burirhat, respectively.Bangladesh J. Agril. Res. 42(4): 707-714, December 2017

A field experiment was conducted during kharif, 2005 at Agricultural Research station, Devihosur, Haveri, Karnataka to assess the progress of powdery mildew at different time interval of sowing dates. Totally 20 different dates of sowings were imposed in the experiment at an interval of 10 days. The crop sown on last week of May to mid of June recorded minimum disease severity compared to rest of the date of sowings. This clearly indicated that crop sown during this period suffers less, which may be due to low inoculum potential, whereas late sown crop suffers more because of the readily available inoculum in the early sown crops. Low disease severity in last week of May to mid of June sowing may be attributed to the non-congenial weather factors for the development of the disease.

Background: Bio-fortification, the process of integrating nutrients into food crops, provides a sustainable and economic way of increasing the density of micronutrients in important staple crops. Agronomic bio-fortification is the easiest, practicable and fastest way for bio-fortification of pulse grains with Fe, Zn, or other desirable micronutrients. Increasing micronutrient rich foods and improving dietary diversity will substantially reduce micronutrient disorders.Methods: A field experiment was conducted during the post rainy seasons of 2015, 2016 and 2017 at Zonal Agricultural Research Station, Kalaburagi, University of Agricultural Sciences, Raichur (Karnataka) to know the effect of soil and foliar fertilization of Zn and Fe on chickpea genotypes. Two genotypes (Annigeri 1 and JG 11) and six fertilization treatments (Control, 0.5% Zn, 0.1% Fe, Zn + Fe, seed treatment with 2 g Zn kg-1 seeds and soil application of Zn) were tested in medium black soils in split plot design with three replications.Result: The pooled data of three seasons indicated that the genotype JG 11, performed better than Annigeri 1 in terms of seed yield (1309 kgha-1), net returns (₹ 31634ha-1) and B: C ratio (2.52). On biofortification of Zn and Fe, foliar fertilization of Zn @ 0.5% + Fe @ 0.1% at flowering stage recorded significantly higher grain yield (1321 kgha-1), net returns (₹ 31179ha-1) and B: C ratio (2.44) over rest of the treatments. Further, foliar fertilization of Zn + Fe had significant influence on nutrient concentration (Zn and Fe) in chickpea grains. Thus, it could be concluded that combined biofortification of Zn + Fe to chickpea crop could be the viable agronomic intervention for getting higher productivity and nutritional security.
